Abstract

Tourism activities are more likely to bring positive impact on the economy of the society. However, if managed poorly, the tourism activities may also bring a bad luck to the region. One of the negative impacts is the excessive unmanaged waste. The excessive waste may create problems that harm the environment and affect the society well-being. This paper aims to examine the potential of sustainable waste management practice in tourism area in Lombok, West Nusa Tenggara. This paper also intent to specifically examine the potential of community participatory aspect in sustainable waste management. This research uses Participatory Rural Appraisal (PRA) methodology to assess the primary data. Additionally, further analysis of secondary data is also added. The research is conducted in tourism area in Saribaye village, Lingsar, West Nusa Tenggara province. The results show that Saribaye village residents still lack of enviromenment awareness and the infrastructure is still far from adequate to support a sustainable management practice. However, the Saribaye village community have a high willingness to learn about the sustainable waste management practice and their current demographic structures may support the sustainable waste management development in the village.

Abstract

Kepulauan Indonesia merupakan wilayah yang mendapatkan curah hujan sepanjang tahun, namun jaringan stasiun pengukuran curah hujan di wilayah ini tidak sepadat atau sebanyak seperti di benua besar lainnya. Oleh karena itu, satelit pengamatan curah hujan merupakan solusi terbaik untuk pengamatan dengan cakupan temporal dan spasial yang memadai. Tujuan dari penelitian ini adalah untuk validasi dan prediksi curah hujan bulanan berdasarkan data satelit Tropical Rainfall Measuring Mission Precipitation Radar (TRMM PR). Data yang digunakan adalah curah hujan bulanan dari satelit TRMM PR Level3A25 dan in situ data dari BMKG selama periode tahun 2004 - 2008. Hasil validasi menunjukkan bahwa data satelit memberikan nilai lebih rendah dari data observasi, kecuali di wilayah anti-monsunal ( C) dimana data satelit memberikan nilai lebih besar dari data observasi. Pola time series rata-rata hujan bulanan berdasarkan 39 lokasi selama periode lima tahun (2004-2008) menunjukkan pola yang sangat mirip dengan data observasi, dengan memberikan nilai korelasi yang tinggi (r = 0,82-0,98) dan RMSE (Root Mean Squared Error) kurang dari SO (mm/bulan). Hasil prediksi curah hujan bulanan dengan menggunakan metode ARIMA (Autoregressive integrated moving average) menunjukkan nilai yang lebih besar dari data observasinya dan pola curah hujan bulanannya untuk periode satu tahun (Januari-Desember 2009) memiliki pola kemiripan dengan data observasi.

Abstract

Indonesia as an archipelagic country has the potentiality of a huge fishery resources and high biodiversity. Fishresources in the waters can be estimated by knowing the content of the primary production (PP) of these waters.The aim of the research are to estimate the variability of environment parameter (SST and Chl-a concentration)and to estimate of PP and fish production (FP), derived from satellite around Indonesia Archipelago.The research was conducted in nine of Indonesia Fisheries Management Area from 2004 to 2006. The PPwas calculated by Vertically Generalized Production Model (VGPM), which was introduced by Behrenfeld andFalkowski (1997a). The model introduced by Pauly and Christensen (1995) calculated the FP. The estimationof FP from model was compared to the FP data from the Department of Marine and Fisheries Resources ofIndonesia.In the territorial waters of Indonesia Archipelago the highest variations of average SST and Chl-a was estimatedat Arafuru Sea, whereas the lowest variation was estimated at Sulawesi Sea and Pacific Ocean. The total annualfish production from the model showed the highest and the lowest values were estimated at Indian Ocean(1,614,135.44 tons) and Malacca Strait (268,305.64 tons), respectively. On the other hand, the total annualfish production from Department of Marine and Fisheries Resources of Indonesia showed the highest and thelowest values were estimated at Java Sea (850,151 tons) and Banda Sea (198,078 tons), respectively. The highestcorrelation between fish production from satellite data and the data from Department of Marine and FisheriesResources of Indonesia was found at Arafuru Sea with R = 0.97. The nine fisheries areas of Indonesia during2004 to 2006 were categorized as fully until over exploited fishing zone.
